INTEGRAL OVERFLO'W AND WAETE-VALVE THEREFOR.

. Elpecification of Letters Patent.

Patented Oct. 13, 1914.

To all whom it may concern:

Be it known that I, WILLIAM A. HENN, a citizen of the United States, residing at Evansville, county of Vanderburg, and State of Indiana, have invented certain new and useful Improvements in Integral Overflows and Waste falves Therefor, of which the following is a specification.

This invention relates to integral overflows and waste valves therefor.

Among the objects of the present invention are the provision of a novel overflow and waste valve for lavatories and bathtubs which will be simple, durable, inexpensive of manufacture, quickly and easily opened or closed and adapted for complete removal for purposes of cleaning, when nec essary or desired.

Another object is to obviate the provision of several joints which are commonly considered necessary in connection with waste valves used for lavatories and bath-tubs; a still further object is to provide, in connection with an integral overflow chamber of a lavatory or bath-tub, an improved waste valve which may be quickly and easily removed from the overflow chamber to permit the entire inner glazed surface of the integral waste chamber to be easily cleaned, thus enabling insanitary accumulations of foreign material to be removed at any time.

The invention consists of the constructions and combination particularly pointed out in the appended claims.

In the accompanying drawings: Figure l a perspective of a lavatory bowl, in section, showing the waste and overflow valve in position; Fig. 2. a detail perspective of the waste and overflow valve; Fig. 3, side elevation at right angles to 2; Fig. 4, a detail perspective of the spud or seat; 5, a similar view of the upper fitting which guides and supports the waste valve;

Fig. 6, a plan view showing the flange or seat for the cam; and Fig. 7, a detail vertical section thereof. I

A portion of the lavatory is shown at 1, there being provided an integral overflow or waste chamber 2 which is in communication with the lavatory bowl solely throughthe drain openings 3. The part of the lavatory which has the chamberQ being integral with the lavatory, there are no joints to catch and cause accumulation of foreign material and no metallic partsto corrode. The chamber 2 is preferably tubular and smooth throughout so that there are no ledges nor projections to catch foreign material draining from the lavatory bowl 1 nor anything to prevent thorough cleansing of the chamber and the walls of the latter are glazed so that perfect sanitation is insured. The opening 1 is for the passage of the fitting orwater faucet.

Extending through the contracted lower end 5 of chamber 2, is the externally screwthreaded spud'6 which is adapted to be attached to the waste or drain pipe. The upper end of this spud is provided with a downwardly tapered or concaved head 7 whose outer margin snugly fits the walls of the chamber 2, and with a ground, tapered seat 8. In consequence, there is no shelf or ledge provided for the accumulation of foreign material as all of such tends to drain with thewater off of the part 7 and into the seat 8. Furthermore, the seat 8 provides a tight joint with the waste valve. The head or flange 7 of the spud rests upon a washer or gasket 9. A nut 10 clamps the spud in position, leaving a sufficient portion of the latter projecting for the attachment of the waste pipe. i

The top of the bowl 1 is preferably countersunk at 11 around the mouth of the chamber 2 to form a seat for the flange 12 of the nut 13 which is internallyscrew-threaded'and serves as a guide for the waste valve. The support 14: forthe waste valve has a lower outwardly extending flange 15 and an internal flange or, cam seat 16 having in clines 16' and flat crests 16", and it is externally screw-threaded at 17 to engage the internal screw-threads of the guide. Surrounding the member 1 1 is an expansible gasket 18, preferably of rubber or rubber composition, against which the guide 13 presses, when it is screwed up, to force the gasket 18 outward into suitable contact with the walls of the chamber 2. The guide 13 and support 1-1, with the gasket 18, may be removed as a unit.

The waste and overflowvalve 19 is tubular and provided at its lower end with a rounded tip 20 which is received inthe seat 8 andis ground so that the two fit tightly together, but at the same time, permitting the waste valve 19 to be readily raised. The.

concavity of the seat 8 and the distance the part 20 enters into it, naturally cause the waste valve to seat itself when lowered. The waste valve 19 is provided with relatively large openings or ports 21 in its upper portion at a height which will permit the lavatory bowl 1 to be suitably filled, but beyond which filling cannot occur as the water will then pass through the drain openings 3 and into chamber 2 through ports 21 and down through the hollow waste valve 19 into the drain pipe. The upper part of the waste valve is provided with a pair of oppositely disposed duplicate double cams 22 whose lower edges are adapted to ride or bear upon the inclines 16 and to rest on parts 16 of flange or cam support 16, the latter being open at 16. The upper part 23 of the waste valve is of larger diameter than the part having the openings 21 and said part snugly yet easily fits the interior of the guide 13 and above it is surmounted by a knob or handle 24 for the convenient turning or raising of the waste valve.

Normally the parts are as shown in Fig. 1. WVater in the basin or lavatory 1 upon reaching a predetermined level, will waste or overflow through the ports 21, keeping the supply in the basin substantially constant. To drain the bowl 1, the knob 24 is turned, whereupon the cams 22 ride upon the cam seat 16 until the crests 25 are supported by said seat parts 16*, whereupon the waste and overflow valve is held in suspended position, and the water passes through the drain openings 3 direct into the drain pipe, through spud 6. If the crests 25 are not brought so they will rest upon the cam seat parts 16 the inclination and curvature of the cams 22 and 16 causes the waste valve to automatically seat itself, due to its weight as the curved surfaces of the cams do not prevent such seating by gravity. Consequently, if the knob 24 is only turned slightly and held until the water drains out of the bowl 1, the release of said knob will cause the waste valve to immediately reseat itself.

On the waste valve there is provided a pin or projection 26 which is adapted to engage the under side of the cam seat 16 when the valve is raised too high and thus prevent the valve from being pulled out of its guide 13. If it is desired, however, to remove the waste valve and the parts 13, 16 and 18, a sufficient pull on the knob 24 will cause the pin 26, by its engagement with the seat, 16, to pull the waste valve and said parts completely out of the chamber 2, whereupon the latter may be cleaned or flushed, and consequently it is possible at anytime to clean out said chamber without having to call in a plumber or skilled workman.

Having thus described my invention, w rat 1 claim as new and desire to secure by Letters Patent, is:

1. A lavatory or bath-tub having an overflow and waste chamber whose upper part is internallv smooth and unbroken, in combination with a valve seat for the lower part of said chamber, a removable guide and support frictionally secured in the upper, smooth, internal part of said chamber, and a waste and overflow valve adapted to ensaid seat and which passes through said guide and support, and means on the valve adapted to engage said guide and support when the valve is su'tiiciently raised, whereby said guide and support may be bodily removed with said valve from said chamber on suliiciently high raising of said valve.

2. A lavatory or bath-tub having an overflow and waste chamber whose upper part is internally smooth and unbroken, in combination with a valve seat for the lower part of said chamber, a removable guide and support which has an external expansible gasket, an internal cam support, and means for expanding said gasket, a waste and overflow valve adapted to rest on said seat, said valve being slidable and rotatable in said guide and support and provided vith a cam adapted to cooperate with said cam support, and means on the valve adapted to engage said guide and support when the valve is sufficiently raised, whereby the guide and support may be bodily pulled out from said chamber.

3. A lavatory or bath-tub having an overflow and waste chamber whose upper part is internally smooth and unbroken, in combination with a valve seat for the lower part of said chamber, a removable valve support having external and internal ledges, an expansible gas at surrounding the support and resting on the external ledge aforesaid, a valve guide having a screw connection to the support and arranged to expand the gasket against the smooth and unbroken wall of the chamber, and a waste and overflow valve adapted to rest on said seat, said valve being slidable and rotatable in said guide and support, and means on the valve adapted to engage the internal ledge to support the valve, said valve being adapted, when sufficiently raised, to bodily pull the support and guide from the chamber.

In testimony whereof, I hereunto aflix my signature in presence of two witnesses.
